LINOLEUM-STRETCHER.

Specificationof Letters Patent.

Patented Aug. 8, 1916.

Application filed October 5, 1915. Serial No. 54,145.

To (ZZZ whom it may concern:

Be it known that we, Ross L. HAUGH and IVILLIAM G. HAUGH, citizens of the United States, residents of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Linoleum- Stretchers, of which the following is a specification, the principle of the invention being herein explained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.

Our invention relates to linoleum stretchers such as are illustrated in Patent No. 1,148,965, issued to us August 3, 1915.

The object of the invention is to provide for such linoleum stretcher an improved locking means whereby both the base and clamping-members may be fixed relatively to each other.

The said invention consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawing and the following description set forth in detail certain means embodying our invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be employed.

In said annexed drawings: Figure 1 represents a plan of a stretcher embodying our invention, showing a. piece of linoleum placed therein. Fig. 2 represents a side elevation of such stretcher showing a piece of linoleum placed therein and also showing the locking pawlinits disengaged position. Fig. 3represents a view similar to that of Fig. 2, but showing the locking pawl in its engaged position.

The illustrated embodiment of our invention is in its general construction the same as that shown, described and claimed in the above mentioned patent, and includes the base-member 1 and the clamping-member 4, the specific forms and arrangement of which form no part of this invention and hence need not be further described. In the previously patented device, a pawl 10 is shown mounted upon the extension 5 forming the handle and this pawl may engage any one of a series of ratchet teeth 9 so as to lock the two members together. In our improved device, however, we provide the rearwardly extending front portion of the basemember l with a slotted lug 11 in which 1s seated a pin 12 forming a journal for a pawl 13. This pawl is curved to form a cam surface 14 which when the pawl is in its lowered or engaging position, rests upon the surface 15 of the clamping-member 4 and engages same frictionally. It will be seen that by means of this construction any tendency of the clampin -member 4 to recede from the member 1 causes the pawl 18 to be wedged between the clamping-member and the lug 11.

By means of the above described construction, a greater range of positions in which the two members may be clamped is provided as compared with the ratchet and pawl construction of the previously mentioned patent, inasmuch as it will be seen that in the latter the number of positions in which the two parts may be secured is limited by the number of teeth 9. Our improved construction therefore provides a very much more convenient means for effecting the locking of the two members, as will be readily understood by those skilled in the art.

Having fully described our invention, what we claim and desire to secure by Letters Patent is 1. In a linoleum stretcher, the combination of a base-member; a clamping-member pivotally mounted upon said base-member and adapted to secure the linoleum between it and the latter; and a locking pawl mounted upon said base-member and adapted to engage said clamping-member so as to fix the latter and said base-member relatively to each other. i

2. In a linoleum stretcher, the combination of a base-member; a clamping-member pivotally mounted upon said base-member and adapted to secure the linoleum between it and the latter; and a locking pawl mounted upon said base-member and adapted to frictionally engage said clamping-member so as to fix the latter and said base-member relatively to each other.

3. In a linoleum stretcher, the combination of a base-member having an upwardly and rearwardly extending front portion; a

clamping member having its forward end pivotally secured upon the rear extremity of said frontportion; said forward end be ing upwardly and rearwardly curved and terminating in an extension forming a handle; and a pawl pivotally mounted upon the end of said rearwardly extending front ROSS -L.
